parts drawing.

NOTE: Always use Genuine Graco Parts and Acces-

sories, available from your Graco distributor. If you

supply your own accessories, be sure they are ade-

quately sized and pressure rated for your system.

Fig. 2 is only a guide for selecting and installing sys-

tem components and accessories. Contact your Graco

distributor for assistance in designing a system to suit

your particular needs.

Grounding

WARNING

FIRE AND EXPLOSION HAZARD

Before operating the pump, ground the

system as explained below. Also read

the section FIRE AND EXPLOSION

HAZARD on page 4.

Although water generally provides a natural electrical

ground, the following equipment must be grounded if

the cleaning chemicals are volatile.

1. When cleaning in enclosed areas, such as storage

tanks, locate the pump and air compressor outside

the area and well away from it. Provide adequate

ventilation. If the area you are cleaning has stored

flammable materials, take appropriate precautions

to avoid static sparking. Consult your local codes.

2. Pump: use the ground wire and clamp (supplied).

See Fig. 1. Loosen the grounding lug locknut (W)

and washer (X). Insert one end of the ground wire

(Y) into the slot in lug (Z) and tighten the locknut

securely. Connect the other end of the wire to a

true earth ground. Order Part No. 237569 Ground

Wire and Clamp.

0720

Fig. 1

3. Air and fluid hoses: use only electrically conductive

hoses.

4. Air compressor: follow manufacturer’s recommen-

dations and local codes.

5. Spray gun: ground through connection to a prop-

erly grounded fluid hose and pump.

6. Fluid supply container: follow your local code.

7. Object being sprayed: follow your local code.

8. Solvent pails used when flushing: follow your local

code. Use only metal pails, which are conductive,

placed on a grounded surface. Do not place the

pail on a nonconductive surface, such as paper or

cardboard, which interrupts the grounding continu-

ity.

9. To maintain grounding continuity when flushing or

relieving pressure, hold a metal part of the spray

gun firmly to the side of a grounded metal pail,

then trigger the gun.

Mounting the Pump

Mount the pump (A) to suit the type of installation

planned. The pump dimensions and mounting hole

layout are shown on page 23.

308117

Installation

System Accessories

WARNING

A bleed-type master air valve (D) and a fluid drain

valve (J) are required in your system. These acces-

sories help reduce the risk of serious injury, includ-

ing fluid injection and splashing of fluid in the eyes

or on the skin, and injury from moving parts if you

are adjusting or repairing the pump.

The bleed-type master air valve relieves air trapped

between this valve and the pump after the air is

shut off. Trapped air can cause the pump to cycle

unexpectedly. Locate the valve close to the pump.

The fluid drain valve assists in relieving fluid pres-

sure in the displacement pump, hose, and gun.

Triggering the gun to relieve pressure may not be

sufficient.

Air and Fluid Hoses

Be sure all air and fluid hoses are properly sized and

pressure-rated for your system. Use a 1/2 in. (13 mm)

ID (minimum) air hose (H). Connect a fluid hose (K) to

the pump’s fluid outlet. Fluid hoses must have spring

guards on both ends. Connect a fluid suction hose (M)

to the pump’s 3/4 npt(f) fluid intake.

Air Line Accessories

Install the following accessories in the order shown in

Fig. 2, using adapters as necessary:

 An air line lubricator (C) provides automatic air

motor lubrication. For manual lubrication, see page

10.

 A bleed-type master air valve (D) is required in

your system to relieve air trapped between it and

the air motor when the valve is closed (see the

WARNING at left). Be sure the bleed valve is easily

accessible from the pump, and is located down-

stream from the air regulator. Order Part No.

113333.

 A pump runaway valve (B) senses when the

pump is running too fast and automatically shuts off

the air to the motor. A pump which runs too fast can

be seriously damaged.

 An air regulator (E) controls pump speed and

outlet pressure by adjusting the air pressure to the

pump. Locate the regulator close to the pump, but

upstream from the bleed-type master air valve.

 An air line filter (F) removes harmful dirt and

moisture from the compressed air supply.

 A second bleed-type air valve (G) isolates the air

line accessories for servicing. Locate upstream

from all other air line accessories.

Fluid Line Accessories

Install the following accessories in the positions shown

in Fig. 2, using adapters as necessary:

 A fluid drain valve (J) is required in your system

to relieve fluid pressure in the hose and gun (see

the WARNING at left). Install the drain valve point-

ing down, but so the handle points up when

opened. Order Part No. 235992.

 A Hydra-Clean spray gun (L) dispenses the

cleaning fluid.

Operation

Pressure Relief Procedure

WARNING

SKIN INJECTION HAZARD

The system pressure must be manually

relieved to prevent the system from

starting or spraying accidentally. Fluid

under high pressure can be injected through the

skin and cause serious injury. To reduce the risk of

an injury from injection, splashing fluid, or moving

parts, follow the Pressure Relief Procedure

whenever you:

 are instructed to relieve the pressure,

 stop spraying,

 check or service any of the system equipment,

 or install or clean the spray tips.

1. Lock the gun trigger safety.

2. Close the bleed-type master air valve (D, required

in your system).

3. Unlock the gun trigger safety.

4. Hold a metal part of the gun firmly to the side of a

grounded metal pail, and trigger the gun to relieve

pressure.

5. Lock the gun trigger safety.

6. Open the drain valve (J, required in your system),

having a container ready to catch the drainage.

7. Leave the drain valve open until you are ready to

spray again.

If you suspect that the spray tip or hose is completely

clogged, or that pressure has not been fully relieved

after following the steps above, very slowly loosen the

tip guard retaining nut or hose end coupling and relieve

pressure gradually, then loosen completely. Now clear

the tip or hose.

Packing Nut/Wet-Cup

WARNING

To reduce the risk of serious injury whenever you

are instructed to relieve pressure, always follow the

Pressure Relief Procedure at left.

Keep the packing nut/wet-cup (15) filled with Graco

Throat Seal Liquid (TSL) or compatible solvent, to help

prolong the packing life. Adjust the packing nut weekly

so it is just tight enough to prevent leakage; do not

overtighten. See Fig. 3. Relieve the pressure before

adjusting the packing nut.

Flush the Pump Before First Use

The pump is tested with lightweight oil, which is left in

to protect the pump parts. To prevent contamination of

the cleaning solution, flush the pump with a compatible

solvent before using it. See Flushing on page 10.

Mixing the Cleaning Solution

If you are adding a cleaning chemical to the water, mix

it thoroughly with a few gallons of water in a separate

container before adding to the drum. Be sure all par-

ticles are well dissolved. Read and follow the chemical

manufacturer’s recommendations on mixing and

application of the solution.

Fill the drum with water and the desired, premixed

cleaning solution.

9308117

Operation

Starting and Adjusting the Pump

WARNING

Moving parts can pinch or amputate your fingers or

other body parts. When air is supplied to the motor,

the air motor piston (located behind the air motor

plates) moves. See Fig. 3. Therefore, never oper-

ate the pump with the air motor plates (P) re-

moved.

1. See Fig. 2 on page 7. Close the air regulator (E),

bleed-type master air valve (D), and fluid drain

valve (J). Do not install the spray tip yet!

2. Place the suction kit (M) into the fluid supply drum.

3. Hold a metal part of the spray gun (L) firmly to the

side of the supply drum and hold the trigger open.

4. Open the pump’s bleed-type master air valve (D).

5. Slowly open the air regulator (E) until the pump

starts, about 40 psi (2.8 bar).

6. Cycle the pump slowly until all the air is pushed

out and the pump and hoses are fully primed.

7. Release the spray gun trigger and lock the trigger

safety. The pump should stall against pressure

when the trigger is released.

8. With the pump and lines primed, and with ade-

quate air pressure and volume supplied, the pump

will start and stop as the spray gun is opened and

closed.

WARNING

To reduce the risk of serious injury whenever you

are instructed to relieve pressure, always follow the

Pressure Relief Procedure on page 8.

9. Relieve the pressure. Install the tip guard and

spray tip in the gun, as explained in the gun manu-

al.

WARNING

COMPONENT RUPTURE HAZARD

To reduce the risk of overpressurizing

your system, which could cause compo-

nent rupture and serious injury, never

exceed the specified Maximum Incoming Air Pres-

sure to the pump (see the Technical Data, on

pages 21 and 22).

10. Use an adequately sized air regulator (E) to control

the pump speed and the fluid pressure. Always

use the lowest air pressure necessary to get the

desired results. Higher pressures waste fluid and

cause premature wear of the pump packings and

nozzle.

CAUTION

Do not allow the pump to run dry. It will quickly

accelerate to a high speed, causing damage. If your

pump is running too fast, stop it immediately and

check the fluid supply. If the container is empty and

air has been pumped into the lines, refill the con-

tainer and prime the pump and the lines, or flush and

leave it filled with a compatible solvent. Eliminate all

air from the fluid system.

other damage, which can cause premature pack-

ing wear and leaking. To check, run a finger over

the surface or hold the part up to the light at an

angle.

10. Be sure the ball seats of the piston (14) and intake

valve housing (13) are not chipped or nicked.

Displacement Pump Reassembly

1. Lubricate the throat packings and install them in

the outlet housing (16) one at a time as follows,

with the lips of the v-packings facing down: the

male gland (6*), two neoprene v-packings (9*), one

UHMWPE v-packing (19*), and the female gland

(8*). Apply thread lubricant and install the packing

nut (15) loosely. See Detail A of Fig. 5.

2. If you removed the cylinder (11), be sure to replace

the o-ring (4). Lubricate the o-ring and apply

thread lubricant to the cylinder, then reinstall the

cylinder in the outlet housing (16).

3. Lubricate the piston packings and install them onto

the piston stud (14) one at a time in the following

order, with the lips of the v-packings facing up: the

female gland (27*), one UHMWPE v-packing (25*),

one neoprene v-packing (26*), one UHMWPE

v-packing (25*), the male gland (24*), the shim

(29*), and the washer (23*). See Detail B of Fig. 5.

4. Screw the piston stud (14) onto the piston mount-

ing stud (28). Torque to 50–70 ft-lb (68–95 Nm).

Install the piston ball (2*) on the piston seat. Slide

the ball stop pin (10*) into the desired set of holes,

and secure with the cotter pin (1*).

5. Place the flats of the displacement rod (7) in a

vise. Screw the piston assembly onto the displace-

ment rod. Torque to 50–70 ft-lb (68–95 Nm).

6. Insert the displacement rod (7) into the bottom of

the cylinder (11), being careful not to scratch the

cylinder. Push the rod straight up until it protrudes

from the packing nut (15).

7. Install the ball (2*), guide (22), o-ring (12), and ball

stop pin (5*) in the intake valve housing (13). Place

the intake valve assembly in the locking ring (17).

Apply thread lubricant to the locking ring and

cylinder (11), and screw the ring onto the cylinder.

8. Reconnect the displacement pump to the air motor

as explained on page 13.
